Definitions
- Heating device for frost-sensitive plants such as grapevines or fruit trees
- the invention relates to a heating device for frost-sensitive plants such as vines and orchards, in particular for use when frost occurs in spring while the plants are sprouting.
- the plants are now covered or frost-sprinkled or the air is fogged or smoked, artificially mixed or even heated.
- anti-freeze candles are used, for example, which consist of largely smoke-free stearin from renewable raw materials, so-called stopgels, which are filled in tubs.
- stopgels which are filled in tubs.
- one bucket is sufficient for 2-3 nights of frost, whereby 200-300 frost protection candles per hectare have to be lit if frost is expected to be -2 to -3 ° C.
- Frost protection candles offer protection even when there is wind frost. Shortly after lighting the fire, the temperature is increased by 1.5 ° C. If the air temperature reaches a critical level, the flames are suffocated with a sealing lid.
- frost protection candles The disadvantage of frost protection candles is that a significant increase in temperature can now be achieved in the immediate vicinity and the lateral radiation is relatively low. This is why a very large number of frost protection candles are needed to protect larger vines. If there is a longer period of frost, the stocks of frost protection candles will run out very soon. Furthermore, the effectiveness of frost protection candles is very limited and only major damage can be reduced.
- the present invention has the object to provide a Bankungsvorrich device for frost-sensitive plants such as vines and fruit trees, which In comparison to the methods used today, it causes a more even heat radiation and a higher temperature increase in the air.
- the heating device for frost-sensitive plants has an upwardly open container made of sheet metal with a bottom formed as a perforated plate and a side wall which extends upwards from the circumferential edge of the bottom.
- the upper opening of the container is larger at the upper edge of the side wall than the area of the bottom.
- the heating device has at least one ventilation pipe, the ventilation pipe extending vertically upwards from an opening in the floor, the diameter of the opening corresponding to the diameter of the ventilation pipe.
- the ventilation pipe furthermore has a plurality of openings each arranged in the pipe wall.
- the heating device When frost threatens, the heating device is filled with fuel, for example pressed wood pellets, placed near the plants to be protected and lit.
- the heating device according to the invention has the advantage that, compared to the antifreeze candles used hitherto, it generates a significantly larger and more uniform radiation of heat. This is based on the one hand on the widening shape of the side wall and on the placement of the at least one ventilation pipe, which introduces air into the fuel and enables complete combustion of fuel. In addition, evenly distributed air enters the fuel in the container through the bottom of the container, which is designed as a perforated plate. As a result, the heating device is environmentally friendly in that it hardly emits any harmful substances or fine dust.
- the heating device can generate sufficient heat for several hours, whereby plantations such as vineyards or orchards can be protected from night frost.
- the side wall is upwardly widening, in a special embodiment it is realized conically. Such a shape optimizes the uniform radiation in all directions.
- the heating device has a centrally arranged ventilation pipe. This ensures a more even and, in particular, complete combustion of the fuel.
- the heating device has, in addition to the centrally arranged ventilation pipe, one or more further ventilation pipes, which are arranged parallel to the centrally arranged ventilation pipe and also have several openings each arranged in the pipe wall of the ventilation pipes.
- the ventilation pipes open at their lower end into openings in the floor, these openings corresponding to the diameter of the ventilation pipes.
- the floor thus also has larger openings over which the ventilation pipes are placed.
- the several ventilation pipes are of different lengths.
- the ventilation pipes are closed at their upper end. This increases the lateral air supply into the fuel and favors the lateral heat radiation of the heating device.
- the heating device has a plurality of openings distributed over its circumference in the side wall in its lower region.
- the openings are preferably arranged above the floor.
- the heating device in the unte Ren area of the container has several recesses which start from the lower edge of the side wall and extend to a level of the floor.
- the Fleizungsvorraum has a transverse strip which extends over the open end of the container and is attached to the Obe Ren end of the centrally arranged ventilation pipe.
- several heating devices can be set up in a row and air distribution pipes are arranged vertically above the heating devices. to distribute the hot air generated by the heating devices in a horizontal direction over the vineyard or over the orchard.
